Root Cause

Powdered infant formula is not sterile and can contain Cronobacter sakazakii, which causes necrotizing enterocolitis, meningitis, and sepsis in neonates, with a mortality rate of 40-80%; the WHO recommends water at 158°F (70°C) to kill the pathogen.

Workarounds

  1. 95% success Boil fresh tap water and let it cool for no more than 30 minutes to reach approximately 158°F (70°C). Mix with formula powder immediately, then cool to feeding temperature by holding the bottle under cold running water or placing in an ice bath. Test temperature on your wrist before feeding.

Dead Ends

Common approaches that don't work:

  1. 75% fail

    Using boiled water cooled to 120°F fails because Cronobacter is not reliably killed below 158°F (70°C); it can survive at 120°F for several minutes.

  2. 85% fail

    Using bottled water labeled 'sterile' fails because the formula powder itself may contain Cronobacter; the water temperature must be high enough to pasteurize the powder.

  3. 90% fail

    Adding a probiotic drop to the formula fails because it does not kill Cronobacter and may introduce other risks.
